Product Description: There are certain differences in the welding performance between Q390C coiled plate and steel plate.Firstly, Q390C coiled plate is a high-strength low-alloy structural steel plate with good mechanical properties and welding performance. Its tensile yield strength, tensile strength, and impact performance are all relatively high, while its welding hardness is generally lower. Therefore, Q390C coiled plate maintains good plasticity and toughness during the welding process, resulting in relatively high welding quality.However, compared to Q390C coiled plate, the welding performance of steel plates may differ slightly. Due to the greater thickness of steel plates, larger welding currents and higher heat input are required to achieve good welding results. Additionally, due to the material and structural characteristics of steel plates, issues such as stress concentration and heat-affected zones may arise during welding, leading to unstable welding quality.In terms of welding methods, both Q390C coiled plate and steel plates can be welded using various techniques, such as arc welding, gas shielded welding, and laser welding. However, during the actual welding process, the method must be selected and adjusted based on product requirements and production conditions. For example, high-quality welding methods are necessary for mechanical parts or structural components that need to bear high loads. For large mechanical products or pressure vessels that are subjected to complex stresses, more advanced welding methods and processes are required.Furthermore, in terms of welding materials, both Q390C coiled plate and steel plates can be welded using a variety of materials. For instance, welding wires or electrodes matching the base material can be used. Alternatively, welding materials different from the base material can be employed, but compatibility with the base material and welding quality must be considered.In summary, there are certain differences in the welding performance between Q390C coiled plate and steel plates. Q390C coiled plate offers excellent mechanical properties and welding performance, making it suitable for manufacturing mechanical parts and structural components that need to withstand high loads.

Product Description: As a critical access point and environmental control node, greenhouse doors vary in requirements depending on the type of greenhouse. Therefore, factors such as size, material, opening mechanism, appearance design, construction, and maintenance must be considered during selection. Many farmers often face issues like heat leakage, frequent repairs, and poor wind resistance due to incorrect door choices. Today, we will help you accurately match the right door for different types of greenhouses, ensuring every investment is spent wisely!1. Sunlight Greenhouses/ Seasonal Sheds: Prioritize Thermal Insulation and SealingThese greenhouses rely on natural sunlight for heating, so the door's insulation directly affects the day-night temperature difference. Double-layer composite insulated doors are recommended, with an inner layer of high-density thermal cotton and an outer layer of anti-aging PVC-coated fabric, edged with EPDM sealing strips. In winter, they can reduce heat loss by over 30% and withstand cold northern winds. For those on a budget, roller shutters with added insulation blankets are a cost-effective alternative—rolled up during the day to avoid blocking light and lowered at night to lock in heat tightly.2. Multi-Span Greenhouses/ Smart Greenhouses: Focus on Convenience and IntelligenceWith large areas and frequent access, electric sliding doors are the ideal partner! Remote control allows one-touch operation without manual pushing or pulling. Equipped with infrared sensors, they avoid collisions with crops or machinery. For logistics transport, customized wider and taller versions can accommodate forklifts and trucks. Farmers seeking advanced intelligence can opt for electric doors integrated with the greenhouse control system, automatically adjusting opening duration based on indoor temperature and humidity for unmanned management.3. Seedling Sheds/ Special Crop Sheds: Emphasize Ventilation and ProtectionPrecise ventilation control is crucial during the seedling stage, and mesh composite doors are perfect for this! The outer layer features a 60-mesh insect-proof net to prevent aphids and whiteflies, while the inner layer is a retractable film curtain. On sunny days, the mesh is opened for ventilation and cooling; on rainy days, the film is lowered to block rain. This keeps pests out while maintaining air circulation, protecting seedlings from diseases. Farmers growing high-value crops (e.g., strawberries, grapes) can also choose anti-theft doors with code locks to safeguard their harvest.Choose the Right Material for a Decade of Use: In northern regions, opt for galvanized steel frames with cold-resistant Oxford fabric to withstand snow load and prevent freezing cracks. In southern areas, aluminum alloy frames with waterproof canvas are recommended for their lightweight, corrosion-resistant properties and ability to resist typhoons.Don’t Overlook Sealing Details: Add rubber strips at the door bottom to prevent cold drafts from gaps. Use Velcro or zipper designs on the door frame sides for easy operation and tight sealing, helping maintain constant temperature and humidity inside.Match Load-Bearing Capacity: If the door frequently accommodates agricultural machinery, the frame should support over 500kg, with stainless steel pulleys for smooth sliding and reduced maintenance issues.High-quality greenhouse doors, with their meticulous sealing design, effectively block air convection between inside and outside. In winter, they reduce heat loss and lower heating energy consumption; in summer, they isolate external high temperatures and reduce the operation frequency of cooling systems, cutting energy costs at the root.Additionally, excellent airtightness prevents insects carrying pathogens and dust from entering, reducing the spread of pests and diseases, lowering the risk of crop infection, and decreasing pesticide use. This not only improves crop quality but also reduces planting costs.Clearly, choosing the right greenhouse door is a key step towards energy-efficient and healthy production in greenhouse farming, offering significant economic and ecological benefits for growers. more>

Product Description: Low Temperature Water ChillerUnit DescriptionA low-temperature water chiller designed for low-temperature conditions, composed of two or more independent refrigeration cycles, with a refrigeration temperature typically ranging from -5°C to -50°C. Due to the diversity of products, some production processes and equipment cannot meet actual working condition requirements using normal-temperature water for cooling. Only low-temperature circulating water can fulfill the practical production process requirements, necessitating the use of low-temperature water chillers.Refrigeration PrincipleThe compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant, which enters the condenser. Part of the heat from the refrigerant in the condenser is expelled by external cooling water or cooling fans. The refrigerant releases heat and liquefies into a high-temperature, high-pressure liquid, which then flows through a dryer filter for drying and filtration. It then passes through an expansion valve for throttling (a rapid cooling process) and pressure reduction, liquefying into a low-temperature, low-pressure liquid that enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (water, oil) in the evaporator. During the heat absorption process, the refrigerant temperature remains constant while its volume changes. After absorbing heat, the low-pressure hydraulic refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and enters the condenser, thus completing the entire refrigeration cycle.Two-Stage Refrigeration Cycle SystemThe two-stage refrigeration cycle is developed based on the single-stage refrigeration cycle, with the compression process divided into two stages. Refrigerant vapor from the evaporator enters the low-pressure stage cylinder and is compressed to an intermediate pressure. After intermediate cooling, it enters the high-pressure stage cylinder and is compressed to the condensation pressure before entering the condenser. Generally, when the evaporation temperature is between -25°C and -50°C, a two-stage compressor should be used for refrigeration. The refrigeration system consists of an evaporator, two-stage compressor, oil separator, condenser, intermediate cooler, ammonia receiver, ammonia liquid separator, throttle valve, and other auxiliary equipment, all connected by pipes to form a closed system. The intermediate cooler uses a small amount of liquid refrigerant to vaporize and absorb heat at intermediate pressure, cooling the superheated vapor discharged from the low-pressure stage, reducing the suction temperature of the high-pressure stage, and also cooling the high-pressure liquid refrigerant.Main Components of the Unit:Compressor: The core component of the entire refrigeration system and the power source for the refrigerant.Evaporator: A heat exchange component that relies on the evaporation of liquid refrigerant to absorb heat from the cooled medium.Condenser: Plays a role in the refrigeration process by dissipating heat output by the compressor and allowing the refrigerant to condense.Thermal Expansion Valve: Commonly known as a throttle valve in the refrigeration system.Liquid Receiver: Installed at the evaporator and compressor suction pipe to prevent liquid refrigerant from entering the compressor and causing liquid hammer, serving as a protective component.Refrigerant: R22, R404a, R407c, R134a, and R410a are used as refrigerants in the refrigeration system.To enhance the stability of the water chiller during use, the EU quality management system certification has been actively implemented in the production process, and product quality control is meticulously managed in supplier selection.Features1. Brand-name compressors are selected, with built-in protection, low noise, energy-saving, and durability.2. The electrical components use branded products such as "Schneider," "Siemens," and "LG," ensuring stable machine operation and long service life.3. Imported Italian and Taiwanese water pumps are used, featuring large flow, high efficiency, and durability.4. Equipped with imported digital temperature controllers, controlling water temperature with an accuracy of ±1°C and a set temperature range of 5–50°C.5. Custom non-standard equipment is available, controlling water temperature from -50 to 85±0.1°C, water flow from 1 to 1000L±0.03L, and pressure from 0.1 to 10±0.04Mpa.6. A fully stainless steel thick-walled tank-type evaporator is used, with built-in automatic water replenishment and other devices, low-water-level automatic protection, and an open design for easy and quick cleaning and maintenance.7. The unit has eight major protection functions: power phase sequence protection, leakage protection, compressor overload protection, coil overheating protection, high and low pressure protection, water shortage protection, chilled water flow protection, and anti-freeze protection.8. The condenser of the industrial water chiller is a sleeve type with internal threaded copper tubes, designed reasonably for excellent heat exchange performance. The air-cooled unit's cooling radiator consists of fins and rows of copper tubes, manufactured using secondary flanging fin mechanical expansion tube technology and advanced heat exchanger production lines to ensure product energy efficiency.7. Electrostatic spray-coated shell with European design, aesthetically pleasing and elegant. The exterior panels are designed for quick disassembly and assembly, facilitating use and maintenance.Unit PerformanceThe low-temperature water chiller uses multiple compressors in parallel, each with its own chilled water circuit. All compressors are controlled by a unified microcomputer control system, starting and shutting down one by one. Additionally, all Ninewells brand units are made with imported original parts, resulting in extremely low single-unit failure rates. Combined, these factors ensure stable performance and continuous operation during long-term work.Application Range of Industrial Water Chillers:Low-temperature water chillers are used in hardware processing, casting, chemical industry, electronics, papermaking, printing, leather, jewelry, glass products, aluminum products, vacuum coating, laser processing, cutting processing, scientific research, medical science, pharmaceuticals, electroplating oxidation, food processing, ultrasonic cleaning, plastic products, central air conditioning, constant-temperature bath pools, ice rinks, ink, agriculture, shipbuilding, construction, aquaculture, aerospace manufacturing, automotive manufacturing, and other industries.After-Sales Service1.

Product Description: Working Principle: Generating steam from flue gas or hot water utilizes a large amount of medium-temperature heat source to produce a small amount of usable high-temperature thermal energy. Specifically, it uses medium-temperature thermal energy as the driving force and, under the condition of employing low-temperature cooling water, produces heat that is less in quantity but higher in temperature than the medium-temperature heat source. This transfers part of the medium-temperature heat to a higher temperature level, thereby enhancing the utilization grade of the heat source. In comparison, it does not require a higher temperature heat source to drive the process but does need lower-temperature cooling water.1) Usable waste heat: Generally, waste hot water, exhaust steam, steam, single or multi-component gases or liquids with temperatures above 80°C can be utilized.2) Provided heat medium: A heat medium or steam with a temperature about 40°C higher than the waste heat source (secondary heating at 80°C), not exceeding 175°C, can be obtained.3) Cooling water source: Cooling tower circulating water, process system cooling water, etc.4) Heating COP below 0.5: This means that using 1MW of waste heat can yield approximately 0.46MW of heat medium required for production and daily use. It is equivalent to extracting about 46% of the heat from the waste heat source for utilization, meeting the heat medium needs of production processes and daily life.System Advantages: This system efficiently utilizes waste heat from flue gas or hot water to generate steam, has a wide range of applications, saves costs, reduces energy consumption, and creates maximum benefits for enterprises. more>
